Figure 10-8 Gripper cylinder and adjustment rod
Adjusting Adjustment Rod
Both blades of the gripper should move symmetrically in order for the gripper to close equally. A
system of cylinder and adjustment rod (see Figure 10-8) allows for the proper operation of the
gripper. The cylinder is used to control one side of the gripper while the adjustment rod is used to
control the other side. Since the cylinder and the adjustment rod have the same length, both sides of
the gripper should move symmetrically. While the gripper cylinder does not need to be adjusted, the
adjustment rod may need some adjustment.
